The third line in the screen is used to set the pressure setpoint for evaporation control.
The fourth line in the screen is used to set the pressure differential for evaporation control.

This screen is used to set the min. and max. speed of the fans featured in the external coil, which is expressed
as the voltage at the controller output, and the speed-up time during which the fan controller output is
overridden to its max. value as soon as the condensation control is started. These parameters are used when
both compressors are enabled in the refrigerant circuit.
The second line in the screen is used to set the voltage which corresponds to the max. speed of the fans in
the external coil.
The third line in the screen is used to set the voltage which corresponds to the min. speed of the fans in the
external coil.
The fourth line in the screen is used to set the speed-up time of the fans.

This screen is used to enable the function designed to prevent high pressure alarms in summer mode and the
corresponding parameters. This function overrides the switch-off of one compressor as soon as a specific high
pressure threshold is reached in order to prevent high pressure alarms from triggering.
The first line in the screen is used to enable the function.
The second line in the screen is used to set the condensing pressure setpoint, having reached which a
compressor is switched off.
The third line in the screen is used to set the condensing pressure differential which enables restarting of the
switched-off compressor as soon as the condensing pressure reaches the setpoint minus the differential.
The fourth line in the screen is used to set the delay to compressor switch-off when the pressure setpoint
recorded in the second line is reached.

This screen is used to enable the function designed to prevent low pressure alarms in winter mode and the
corresponding parameters. This function overrides the switch-off of one compressor as soon as a specific low
pressure threshold is reached in order to prevent low pressure alarms from triggering.
The first line in the screen is used to enable the function.
The second line in the screen is used to set the evaporation pressure setpoint, having reached which a
compressor is switched off.
